I knew I'd ignite controversy with this one - I'm just saying that if an experiment were ever conducted along these lines, I'm relatively certain that the results would indicate that nobody could tell the difference.

But I see micah's post down there and I agree that if you continually burn CDs and then rip them again and again and again the quality goes down the toilet. I never burn CDs because I have an mp3 player, so I guess I forgot about that contingency.

And I am a bit obsessive about eventually obtaining the lossless copies of shows, if only because that's what the trading community accepts. So I guess the lesson is, never taking anything I say too seriously.

edit: I hadn't seen that post by monte! That's great, never thought I'd see a Fourier series on a grateful dead forum... what's interesting about that particular series is that although the waves converge pointwise to the square wave, they don't converge uniformly. You can see the little "horns" at the points of discontinuity, and those horns have basically a constant height.

In case I haven't already scared people away with my music theory digressions....

Are you kidding? You won't scare anyone away methinks; why, there have any been threads about Nyquist frequencies (Noise Collector, of course, was involved!), which I had to learn about while analyzing various animal calls and such, back in the days of the Analogic Waveform Analyzer, which was "must have piece of equipment for acoustic analysis of the animal kingdom, costing ~ $15k, in 1979 when I (well, the university) got my first one...of course NOW, a simple program like Canary costing ~ $100 does it all and more! And there are even "free" softward programs that I am sure Monte could tell us about that do the same sorts of analyses.
